I am  thinking of offering a device to measure and record
the compression on a  rotary engine.
Price would be about $60 for the sensor, power supply and  spark plug hole
fitting. It would require a $90 Hytek data aq  module.

Similar systems  from:

http://rotarydiagnostics.com/model_rect-03b.htm

cost $364  + $20 for shipping and handling.

Handy to check the condition of that  engine
before you buy it. Use an impact wrench on the
front e-shaft nut  to turn the engine over.

What do you think?

Sounds interesting, Paul.

I'd be interested if it goes into production
Would like more information

The sensor is an off the Shelf Free Scale product
and we will build a pressure tap that screws into
the lower spark plug hole similar to our pressure
taps that screw into the apex seal lube holes.
There is a picture on the web site near the
bottom of the front page.
You will also get a chunk of silcone hose to
connect the two.
